R-Series 8” Compact Subwoofer in Tuned enclosure
Loud, Clean Bass That Fits Anywhere
The Alpine SBR-S8D4 features Alpine’s Type-R 8″ subwoofer in a custom slot ported enclosure. Ideal for installation in small spaces, its compact size means it can fit virtually anywhere.
The pre-installed subwoofer employs many features typically found in larger models, such as Alpine’s H.A.M.R (High Amplitude Multi-Roll) suspension. This unique design allows greater linear excursion while improving control, to achieve maximum output and outstanding sound quality.
Designed to achieve optimal output, the carpeted enclosure features heavy-duty MDF construction. Plus, stylish brushed aluminium laminate and a robust grill create the perfect balance of stunning aesthetics and practicality.
Alpine’s new 2nd generation R-Series Subwoofers feature enhanced sound performance in an exciting new aesthetic. A larger motor structure featuring double-stacked neodymium magnets and an integrated faraday-ring results in a deeper, clearer and tighter bass while the all-new Kevlar-treated cone ensures this extra performance is reliable – even at higher volumes.
The new EZ-Change twist-lock grille mounting system makes subwoofer installation easier than ever before. The optional grille (KTE-12G), exudes a tough look with the benefit of added protection.
Quality and Performance unrivalled in the industry, Alpine’s new 2nd Generation R-Series continues to be the benchmark in sound quality for the audio enthusiast.
